I think this is what is biting you. You might expect that after
argFunc, one.x would be set to 'place_no_x' and so on. However,
Python's scoping doesn't work like that -- the name one.x is only
rebound in the function's scope, so outside of argFunc (e.g. in your
main printing code) one.x is still bound to 'place_x'.

HTH,
